What is the area of this regular polygon?

a.311.15 m2

b.
622.3 m2

c.
3034.5 m2

d.
6069 m2

The right answer is C.  what you have been given is base length and height for the seven triangles included in this geometric shape as you can see there are seven sides, and thus seven triangles in the entire heptagon. the formula will be: (base(height)/2)(7)= the area of the heptAGON.  Area=the area of each of the triangles within the heptagon. since they all have the same dimensions, your equation will be (30*28.9/2)*7

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width
